Clarifying Concepts in Education and Pedagogy

April 10, 2014 by · No Comments · Pedagogy and Educational Methods, Uncategorized

This post is a preface to my post on Gergory Loewen’s hermeneutic pedagogy.

Much of the empirically based research in education seems fadish.  We must consider that the problem might originate in what Wittgenstein referred to as a conceptual confusion, based on a miss-understanding of how concepts relate to methodology.

‘The existence of the experimental method makes us think that we have the means of solving the problems which trouble us; though problem and method pass one another by.’   In the same way, using the techniques of  mathematical proof cannot solve the fundamental problems of mathematics.  In both cases we must turn back to a deep and sustained examination of the conceptual basis of each discipline. (Wittgenstein and Psychology)

In education today, what is it that we want students to learn, who do we want them to become and what pedagogy do we employ to those ends?  This question is at the conceptual core of education.  To this I have a 3 fold answer.

  1. We want to pass on to the next generation what it means to be a functional person in todays society.  To know the beauty possible in music, the complexity and competing claims in the development of democracy, the depth of self-understanding in Shakespeare, or the ability to evaluate scientific claims.  The beginning of these aims, the first steps, is to be found in the knowledge of facts, theories and disciplinary concepts and languages.  Skills in reading, in numeracy, and in using various discourses.  Histories, common narratives, and cultural traditions.  This is the goal of cultural transmission.  It is not the end, but understanding the culture into which we are immersed is the beginning of any educational journey.
  2. Second, we must do more than “parrot” this knowledge.  We must read not just for comprehension, but to interpret language in multiple way and to understand how it can be directed to different people.  We must have more that the ability to calculate, we must understand how numbers fit a purpose, whether it is making a budget, devising a mathematical proof or evaluating a statistical claim.  We must know more than historical narratives, we must know how they relate to ourselves and to others.  This is extending basic learning and making it function as practical knowledge.
  3. Finally, we must use this knowledge to carve out our own path.  To become the self-reflexive practitioners that are the creative innovators, collaborators, communicators and strategiers; able to solve the problems of  both today and tomorrow.

Once we are conceptually clear on the ontology our students, who we want them to be and to become, then it will be time to address the pedagogy.  How will we make it happen.  This is my corresponding pedagogy.

  1. Direct Instruction monitored for recall of basic facts and knowledge as well as the schema that allow us to efficiently categorize this knowledge base and retrieve it when needed.  (Including both the schematic conceptualizing and the technological scaffolding to enable us to access and find information when it is needed; i.e. Artificial Intelligence)
  2. Performance abilities and project methods that give us the opportunity to engage in practical activity using our knowledge and to be able to participate and be literate in disciplinary discourses.
  3. Opened Ended Projects involving complex problem identification and problem-solving.  The opportunity to demonstrate character and persistence.

Why Performance-based Education is Needed

April 9, 2014 by · No Comments · Pedagogy and Educational Methods, Performance Support

We (have arrived) at a most surprising conclusion: . . . the things supposedly contained “in” (our inner lives) are not to be found “inside” us as individuals at all, but “in” the continuously unfolding relations occurring between ourselves and others (or an otherness), in our surroundings.  (We cannot) hide the contents of our inner lives wholly inside ourselves, for, Like it or not, we “display” them in the unfolding movement of our living out our lives, responsively, amongst others.  . . . we cannot but be immersed in it. (Quoting Wittgenstein) “Only in the Stream of thought and life do words [and our other activities] have meaning”. John Shotter, 1998, Social Construction as Social Poetics

Compare the activities of 2 students.

  • One studies a book, hears a lecture, and memorizes facts and theories of lead-base paint as an environmental hazard, before taking a test of recall.  This is educating the latent mind of a student.  But realistically, how long will this information be available?  How well prepared is that student to be a productive part of society?
  • A second student also studies this book, but is not concerned with recall, confident that the content exists in digital resources that act as a scaffold to their understanding and can be located whenever needed.  This students then participates in a peer discussion locating potential lead problems in their community and strategizing how this problem might be solved including additional research for resources through governmental and environmental organizations.  The students defends their activities and strategies orally and they include a record of the resources they used in devising and supporting their strategies.  They also documents their actions in a digitalized portfolio.  How well prepared is this student to participate in society, to understand this topic in depth and over time, and to be responsible to their peers and their teacher for their engagement and their actions?

This is the educational relevance of Wittgenstein’s preference for finding meaning through practice.  We have an idealized view of cognition, that our knowledge can be contextualized without contextualing cognitive skills.  Knowing something is a cognitive skill.  Being able to apply that knowledge within practice is also a cognitive skill, abet at a much higher functional level of cognition.  This higher functional level represents the difference between project-based learning with performance assessment and lower level pedagogy with recall-based standardized assessment.  Certainly the second student has emerged from this activity as a more capable, confident and engaged person.  This doe not mean that facts and theories are not important.  These types of things make up a significant portion of the discourse that students must have in order to engage each other, as well as the experts in this topic.  But until they have engage responsively with others in authentic situations, this higher level of cognition will not be fully developed and even the lower level knowledge will not be significantly understood.

Locating Performance in Pedagogy

April 5, 2014 by · No Comments · Measurement, Pedagogy and Educational Methods, Practice Validity, Uncategorized

Philosophy has a radical way of approaching and dealing with knowledge – for instance, it tries to overcome doctrines which do not question themselves and to compensate for the progressive drift of using and expanding knowledge only technically. Philosophy tries to understand the world . . ..  From: Lucian Ionel

As Lucian Ionel notes, this is an important part the philosophical method of Gregory Loewen’s Hermeneutic Pedagogy.  It’s yet another way of looking at the educational process and noticing what normally flys under the radar.  Loewen’s method seems to be categorizing pedagogy into three classes: Hexis, Praxis and Phronesis.  These 3, along with Episteme and Techne, form the intellectual foundation of Greek philosophical thought.  Episteme is concerned with aspects of knowledge and Techne is about craft or skills in production, both important, but Hexis, Praxis and Phronesis seem to make up the the core ideas of Loewen’s educational processes. I’m studying his approach and think that it might fit the direction of my recent thoughts about performance assessment.  This post is preliminary, about how my previous thought might map onto Loewen’s framework.

Helix

I will key Helix as repetition and re-production.  It focuses on the passing of cultural knowledge.  In current educational practice, think of Helix as represent the standardized curriculums associated with No Child Left Behind and the Common Core.  These curriculum represent the basic knowledge that is expected by all citizens (re-production) and is (at least partially) achieved through memorization and direct instruction; pedagogy that is high in repetition.  Many current educational practices can be represented by Helix.

Praxis

Praxis, generally understood as practice,  here is keyed as extension.   Think of representing applied knowledge that expands and changes according to the contexts and needs of practice; the learning necessary for practical performance.  This is often considered learning transfer, but in the wake of social cultural learning theory I think of this as extending by adding new learning.  This is not emphasized in current educational practice.  You can see it in activities such as creative writing, service learning or project-based learning, but it is often conceived as an after thought, not as a core educational component.

There are 2 things that should be  included in praxis education to make it more of a core goal of educational practice.  First, at this level you still want to provide lots of structure to these activities and to link them to existing curriculum.  Educational scaffolding can be used as the glue that links the curriculum to the activity structure.  Secondly, bring measurement into these performance activities. Measurement is a core component to education practice.  The inability to satisfactorily measure performance-based practice hurts its standing.  This means development not only in educational practice, but also development in educational measurement.  Note – This does not mean standardized assessment as currently practiced.  See this post on Ontologically Responsible Assessment for more info.

Phronesis

Phronesis is often translated as practical wisdom and it is the second part of my take on performance-based learning.  This is what I consider to involved higher levels of cognitive learning as well as what is often considered character education.  This certainly includes the higher levels of Bloom’s taxonomy, but broken down into more socially relevant skills that are more practice oriented and more socially oriented.  Bloom’s categories are overly individualistic and do not include socially interactive and practice relevant abilities that are becoming increasingly important for today’s workforce.  This is even more true of Bloom’s Affective and Psychomotor Domains which are more closely based on outdated behavioral theory.

Some of the qualities and cognitions to include are: problem identification and solving, creative thinking, situated strategic thinking, self-motivation, persistence, resilience, metacognition and self-directed learning, collaboration, effective situated communication and the ability to form strategic relationships.  For me this is similar to the Praxis level, but it is more open ended and with less structure and less dependence on specific curriculum.  At the praxis level, scaffolding was more knowledge based and emanated from standard curriculum.  At the Phronesis level, we’re moving toward a more skill and abilities foci.  Scaffolding at this level are more socially oriented and come from teachers or peers.

This Phronesis level asks a student to explore self-knowledge; not to just use knowledge in a technical sense, but also in a consciously creative and moral fashion.  This is Lucian Ionel quoting Loewen:

What is gained through this process is what we call self-knowledge: “Phronesis sees through the practicality of repetition and extension by seeing them as rationalizations for the world as it has been. In its subtle but forceful presence, the wisdom of reflective practice asks us to stand outside of the dominion of discourse, the caveat of custom, and move ourselves into the brightest human light of self-understanding anew.”

Where helix and praxis can be scripted (at least to a certain sense in praxis) phronesis is open-ended and reflexive.  It leads to process questions such as: Why is it this way; how have we arrived at this point?  What does or does not make sense here?  Can things be different?  How would you scale a new approach?

These skills and abilities are some of the most important personal qualities in personal success, but fall mostly outside of current educational practice.  They are not only the most difficult to measure, but measures tend to serve different purposes in the educational process.  The overall process is more relational and less mechanistic than at either the Helix or Praxis levels.  These measures must be concieved in more of a joint dialogical nature and less of an automated and behavioral fashion.  This does not mean that we give up on scientific objectivity or become less empirical in measurement.  But it does mean that we do not allow narrow definitions of empirical objectivity to constrict the construct we want to measure.  Narrow (and more traditional) measures represent the “doctrines which do not question themselves” and are the ones who fail “to compensate for the progressive drift of using and expanding knowledge only technically” which Ionel mentioned in the leading quote.

Let’s Bring a Level of Artistry to Building Forms of Digital Life

March 29, 2014 by · No Comments · Pedagogy and Educational Methods, Uncategorized

Matthias Melcher’s post on the digital humanities has got me thinking about extending the ideas from my post here that  referenced Lee Drutman’s ideas on the creativity of quants.

Let’s start with this John Shotter quote about Foucault’s Archeology of Knowledge; ideas about how the world got to be the way it is now.

But now, many take seriously Foucault’s (1972: 49) claim that our task consists of not – of no longer – treating discourses as groups of signs . . . but as practices that systematically form the objects of which they speak.

In many discussions the humanities and the sciences are structurally defined by how they differ from each other.  But step back; distance oneself to see the practice and form of life that normally escapes notice.  People engaged with educational discourses are shaping educational practices (forms of life) and students (their object) much as a painter shapes the forms on his or her canvas.  This is not to critique these practices, but to bring to our attention the artistry that is possible in creating all forms of life: not just painting and literature, but no less in educational practice, data science, or social science.  Also, as participants jointly engaging in these forms of life, let us also bring artistry to the objects of which they speak; us.

Here’s my main point: Data science is about to transform education.  It can take many different forms.  Will we take the notice and expend the effort to add a level of artistry in what we create, or will we blindly stumble through.  Can data be an architectural tool through which we create a more beautiful world.

Unpacking Ontologically Responsible Assessment

March 28, 2014 by · No Comments · Measurement, Pedagogy and Educational Methods, Uncategorized, Validity

In this post I want to unpack the term Ontologically Responsible Assessment mentioned in this post

Why Develop an Ontology:

An ontology defines a common vocabulary for researchers who need to share information in a domain. It includes machine-interpretable definitions of basic concepts in the domain and relations among them.  . . .   There is no one correct way to model a domain— there are always viable alternatives. The best solution almost always depends on the application that you have in mind .  Source

When people say that students need 21st Century skills, what they really mean is that they want to change their ontological commitments as to what students are, and to what they will become.  When we move from a mechanistic factory model of education to a dialogic networked model; we are really changing our ontological commitments from components in a machine to actors in a network.  Ontologies try to clarify questions about the nature of being and becoming a student in the context of educational practice.  I would add (to the typical information systems objectivist account) that an ontology in educational practice also involves recognizing that students are constituted by networked relationships and the various domain discourses within which they interact.  The main difference in this ontology is that (in contradistinction to most information systems ontologies) its organization is not hierarchal and behavioral, but rather contexted, networked and dialogic.  This doesn’t mean there is no place for hierarchal behavioral objectives, just that they no longer form the core of our educational goals.

Why Responsibility:

Depending on whether one believes that reality is objectively given or subjectively / collectively constituted, the understanding of responsibility will differ. This, in turn, has a serious impact on how individuals and collectives can or should use IS (Information Systems).  . . . Reality is thus not given and open to objective discovery but outcome of the intentional activity of perception and interpersonal communication. This means that the dimensions of responsibility must be discovered through communication. (Stahl, 2007 Available from Research Gate or Ontologies, Integrated Series in Information Systems Volume 14, 2007, pp 143-169)

Education can’t be conceived through objective behavioral description, rather, it is conceived in the context of conversational realities.  Students are not cogs in a machine, but are people and the conversational realities where we meet them involves commitments, requirements, privileges, and various other high level latent traits that defy easy objectification.  To be responsible is to jointly actualize an educational program.

What Do I mean by Assessment:

What is the purpose of educational assessment?  Wikipedia speaks about documenting knowledge, skills, attitudes, and beliefs.  Merriam Webster talks about making judgements.  Edutopia talks about assessment as a mechanism for instruction.  I want to focus on another aspects that may seem technical, but I believe gets to the heart of the matter.

What is it that we measure are latent constructs for the most part.  As Michael Kane (2013) frames it:

Test scores are of interest because they are used to support claims that go beyond (often far beyond) the observed performances. We generally do not employ test scores simply to report how a test taker performed on certain tasks on a certain occasion and under certain conditions. Rather, the scores are used to support claims that a test taker has, for example, some level of achievement in some domain, some standing on a trait, or some probability of succeeding in an educational program or other activity. These claims are not generally self-evident and merit evaluation.  Validating the Interpretations and Uses of Test Scores

More than anything else, assessment, at its core, is the process of estimating a latent trait and making it visible.  It is the first step in the analytic process of drawing connections, but we can’t connect the dots until they are visible to us.  There are 2 people for whom this is of primary importance: the teacher and the student.  If we observe the educational practices that involve testing, these are often the last 2 stakeholders that are given consideration, but they should be the first.

Conclusion

This 3 fold understanding of educational assessment includes developing an ontology where assessment practices recognize a full account of the being and becoming of students.  It does not restrict our view to what is easily measured, but essentially meaningless in the bigger picture or final analysis.  Secondly, it is responsible in that assessment is linked to an expectation for engagement that goes beyond behavioral description to fully recognize the full complexity of that student engagement as a dialogic and networked individual.  And finally, it does not use data in a mechanistic fashion, but uses construct measurement to make their joint responsibilities and ontologies visible to teachers and students in everyday educational practice.

A Practice Perspective on the Quants and the Humanists

March 25, 2014 by · No Comments · Philosophy, Practice Validity, Uncategorized

Lee Drutman responded to Timothy Egan’s New York Times Article about creativity and Big Data.

First TE says that companies like Amazon who are based on quantitative methods are not creative because they “marginalized messiness”.  LD responds that “(d)ata analysis and everything that goes into it can be highly creative”, meaning (I guess) that Quants can get down in the mess too.  Both are good points but miss another aspect that unites the arts / humanities and the sciences, and this is the heart of my argument.  They are both creating practices that effect our live in important ways.   The point is that we all create.  It’s not whether we are or are not creative.  It’s a question of what we are creating.  From John Shotter’s Cultural Politics of Everyday Life:

But now, many take seriously Foucault’s (1972: 49) claim that our task consists of not – of no longer – treating discourses as groups of signs . . . but as practices that systematically form the objects of which they speak.

In other words, it’s not wether the Quants are creative, but do their analyses treat me as an object to be controlled, or do they treat me as a human being where the analysis respects my being.  That’s called ontologically responsible assessment.  Again, from Shotter:

I want to argue not for a radical change in our practices, but for a self-conscious noticing of their actual nature.

We should offer people clear and understandable analysis where they can make new connections, but also respects and is responsible to their rights as a person.  Yes, as Lee claims, the sciences and the humanities can work together.  But beyond that, they are both human based social practices.  If we see them as practices a la Foucault, there is much more in common than is different.  They are both not only creative, but they are creating.

Instructionism, Constructionism and Connectivism: Epistomologies and Their Implied Pedagogies

March 24, 2014 by · 1 Comment · M.M. Bakhtin, Pedagogy and Educational Methods, Thinking Skills, Uncategorized, Validity

Ryan2.0′s blog recently hosted a discussion on different pedagogies based on Instructionist, Constructionist and Connectivist  theories of learning.  I tend to see these differences on an epistemological / psychological / psychometrics level.  (I’m an educational psychologist, not a philosopher.)  I think this line of thinking is helpful for exploring some of my recent thoughts.

First a note; I resist labels on learning theories.  A consensus may be developing, but there are so many sub-positions that if you look at 100 constructivist positions, you’ll find 100 different takes (as evidenced by many of the comments on Ryan’s post).  I just find labels unsatisfying as points of reference for communication in learning theories at this time; they convey too little meaning to me.  Tell me what you don’t like about a learning theory; I probably don’t like it either.

What’s the Point

Ryan’s main point is that all of these pedagogical position are evident in current education practices and we should think in terms of “and” not “or”.  This fits with my own view that paradigm shifts should proceed by subsuming or at least accounting for the successful parts of the previous paradigm, while enabling teachers and scientists to move beyond problematic aspects of older theories.  To really understand these different theories, it will be good to see how pedagogy changes as we move from one to the next.  My post here looks at each one of these different theories in terms of epistemology / psychology / psychometrics, and than discuss a place where implied pedagogies are relevant to practice today.

Direct Instruction

I’m not familiar with instructivism per say, but it seems similar to direct instruction, a pedagogy that is associated with positivism / behaviorism.  Direct instruction often uses empirically based task analyses that are easy to measure and easy to employ.  Applied Behavioral Analysis is a specialized operant behavioral pedagogy that is a prime supporter of direct instruction.  Many, if not most classroom use direct instruction in some form today.  It seems like common sense and many teachers may not be aware of the underlying epistemology.

One prominent area where advanced uses of direct instruction is growing is in computer based adaptive learning like the Knewton platform. Students follow scripted instruction sequences. A student’s specific path within the script is determined by assessments that follow Item Response Theory (IRT) protocols.  The assessment estimates a student’s command of a latent trait and provides the next instruction that is appropriate for the assessed level of that trait.  The best feature of Adaptive learning systems is the efficiency in moving students through a large body of curriculum or in making leaps in skill levels like the improvement of reading levels.  Because it is also easy to measure, it’s possible to use advanced psychometric computer analyses.

Critiques of direct instruction can be similar to critiques of behaviorism in general.  Even though test developers are becoming more sophisticated in measuring complex constructs (eg. Common Core), the learning that results from direct instruction can still be seen as lacking in conceptual depth and in the ability to transfer to other knowledge domains.  It also doesn’t directly address many important higher level cognitive skills.

Constructivism

Enter constructivism.  I think of constructionism as beginning with Piaget’s learning through schema development.  Piaget’s individual constructive approach is expanded by social theorists and ends up with embodied theorists or in ideas similar to Wittgenstein’s; that knowledge and meaning are closely linked with how they are used.  Wittgenstein’s early work was similar to the work of logical positivists.  He eventually found that meaning in everyday activities is inherently circular and the only way to break out is not through precision, but to look for meaning in what people are doing and how they are using knowledge.  In some ways it’s like a return to behaviorism, but with a position that is more inline with hermeneutics than empiricism.

I recently saw a presentation of an instructional program (MakerState) based on the Maker / Hacker Space movement that functions much like a constructivist approach to education.

MakerState kids learn by doing, by creating, designing, experimenting, building…making. Our makers respond when challenged to think outside the box, to think creatively and critically, to collaborate with their peers, to problem solve, to innovate and even invent solutions to challenges they see around them.

This program can be founded on the same curriculum as that used in direct instruction when developing maker challenge activities and it can use this curriculum to scaffold maker activities with STEAM principles.  But the outcomes are open ended and outcome complexities are well beyond what is capable through direct instruction.  Learning by doing is more than just an aside.  Making knowledge concrete is actualizing it; taking it from the abstract to make it meaningful, valuable and productive.  But, is this the end of educational objectives; does success in life not require even more.

Connectivism

Enter Connectivism.  I associate connectivism with the work of  George Siemens and Stephen Downs.  I take this post from George as a good summary of Connectivism:

The big idea is that learning and knowledge are networked, not sequential and hierarchical.  . . . In the short term, hierarchical and structured models may still succeed. In the long term, and I’m thinking in terms of a decade or so, learning systems must be modelled on the attributes of networked information, reflect end user control, take advantage of connective/collective social activity, treat technical systems as co-sensemaking agents to human cognition, make use of data in automated and guided decision making, and serve the creative and innovation needs of a society (actually, human race) facing big problems.

I believe this take on Connectivism is modeled on computer and social media networks.  My own take is to include a more biological approach as another major node in connectivism: M.M. Bakhtin, a Russian literary critic known as a dialogic philosopher.  I want to draw this connection because dialogism is a reasonable way to make sense of everyday collective co-sensemaking activity by an organism interacting with its environment.  I see this as understanding the underlying way networks function when biological organisms (i.e., humans) are involved.

One of Bakhtin’s main ideas is heterglossia:

(A)ll languages (and knowledges) represent a distinct point of view on the world, characterized by its own meaning and values. In this view, language is “shot through with intentions and accents,” and thus there are no neutral words. Even the most unremarkable statement possesses a taste, whether of a profession, a party, a generation, a place or a time.  . . . Bakhtin goes on to discuss the interconnectedness of conversation. Even a simple dialogue, in his view, is full of quotations and references, often to a general “everyone says” or “I heard that..” Opinion and information are transmitted by way of reference to an indefinite, general source. By way of these references, humans selectively assimilate the discourse of others and make it their own.

Just as water is the medium that allows fish to swim, language is the medium that facilitates networks.  Rather than focus on words as the base unit, Bakhtin focusses on the utterance as his main unit of analysis.  This is from the main wikipedia Bakhtin article:

Utterances are not indifferent to one another, and are not self-sufficient; they are aware of and mutually reflect one another… Every utterance must be regarded as primarily a response to preceding utterances of the given sphere (we understand the word ‘response’ here in the broadest sense). Each utterance refutes affirms, supplements, and relies upon the others, presupposes them to be known, and somehow takes them into account…

I see this as a detailed account of the Wittgenstein use argument that I used earlier.  I take from a psych perspective: The inner psychological world reflects and models the interaction we have with the world.  Because learning is facilitated by social interaction with other people in dialogue, our mind is structured in a dialogical fashion.  This is to see knowledge as existing not only through network nodes, but nodes that reflect dialogue and inter-connected utterances. (This is similar to structuralism, but goes well beyond it in its implications.) Even when we are learning through self study we structure that study in a dialogical fashion.  When we engage in soliloquy, we posit a general other to which we address our words.  Transferring knowledge is not just cutting and pasting it to another node in the network.  We must also adjust to new intentions, new references, and often to the tastes of a new profession or discipline.  I don’t know what the neurological correlates are to dialogic activity, but cognition at a conscious level (and some aspects of unconscious levels), I see the mind as structured by its interaction with this complex social / speech world.

I don’t yet have a good example of pedagogy that reflects this dialogic connective theory.  It would certainly be activity based and structured more like an open-ended apprenticeship and some sort of performance.  I’m thinking that some relevant learning objectives would include: higher order cognition in unstructured situations (e.g. knowledge transfer, problem identification and solving, creative thinking, situated strategic thinking),  intrapersonal dispositions (e.g. motivation, persistence, resilience, and metacognition like self-directed learning) and interpersonal skills sets (e.g. collaboration, effective situated communication, relationship development).

I think a key to achieving a higher level of connective pedagogy is valid assessment in an area where assessment has proven difficult.  Assessment in this context must also be ontologically responsible to the student.  The purpose of ontologically responsible assessment is not to rank, rate, or judge either students or teachers.  That is a task for other assessments. Instead, ontologically responsible assessment is a way of making ourselves visible, both to ourselves and to others, in a joint student teacher activity that conveys the students history and future horizons.  (Horizon = A future that I can see only vaguely, but contains a reasonable route to achieve, given both the student’s and teacher’s  join commitment to each other and to the path.  Education as a doable, visible, committed and ontologically responsible joint activity by student and teacher.

TI’m neven satisfied with an ending, but this seems like a good jumping off point for another post and another time.  I feel the need for input before going further in this direction.

Seeing Students Develop: From Objective Data to Subjective Achievement

March 10, 2014 by · No Comments · Pedagogy and Educational Methods, Validity

Even though the personalization / individualization of instruction is being driven by objective data in learning platforms, this data can also be used to facilitate a deeper self-understanding  commitment and understanding between the student and the teacher.

To see the future, students and teachers should focus on their horizons.  Horizons here refer to a point in developmental  time that can’t be seen clearly today, but that I can reasonable expect to achieve in the future.  Because many aspects of this developmental journey are both precariousness and dependence on future actions, this joint vision can’t be wishful thinking, but must be clearly framed in terms of privileges and obligations.  When it is treated this way, assessment is not a picture of student achievement, but is a methods for making both student and teacher visible to each other in a way that is rational, meaningful and conducted in an ontologically responsible manner; that is, in a way that is true to who we we want to become (Shotter, 1993).

This model of support begins with valid assessments that are clear and explicit about their  meaning, the underlying values implied and the actual or expected consequences.  The learning process can then be understood from a narrative perspective as well as mathematically.  By referencing empirically supported path models, personalization can include choice, preparing the way for stronger commitment and clarification of learning directions, choices and possibly experiments involving learning directions.

Theis idea is not to suggest that assessment must become less objective, but to recognize that an education process must contribute to the development of a subject.  Educating a student is not like designing a computer chip.  It is about helping an individual actualize their unique capabilities while finding themselves and their place in society.  The Goal of Education is intellectual development.  Approaches that are tethered to a mechanistic model of education will fail in this goal and are not even appropriate in terms of the efficiency by which they may be justified.  Assessment may start with objective visions, but its uses must directly translate to the subjective tasks that are central to both teacher and student.

4 Reasons Adaptive Learning Could Replace High Stakes Standardized Testing (It’s in the Validity)

March 8, 2014 by · No Comments · Uncategorized

I attended a recent nyc edtech meet up at Knewton in NYC. While looking at their promotional materials on their platform it occurred to me that this system has a stronger basis in validity over high stakes standardized testing (HSST).  I know it’s a (big) data driven approach, likely similar to what I was familiar with at Sylvain, except that digitalization allows you to address many more dimensions in the data, to cross-reference different domain skills and to better represent intellectual development over time.  This post is about the validity of big data adaptive learning systems as compared to high stakes standardized testing (HSST).

  1. The easiest distinction to be made is to contrast the “snapshot in time” nature of HSST and the developmental histories of adaptive learning.  Development is the way students and teachers understand school-based learning especially when it’s not linear, but proceeds in fits and starts.  Neither does a snapshot relate to the purposes of assessment.  In adaptive learning error is not judgement, but an excuse for more learning.
  2. This point may seem esoteric but I think important.  HSST must represent an ambitious  construct interpretation, that is, a single HSST question must represent the same learning that is represented in hundreds if not thousands of questions in an adaptive learning system.  And while the assessments in the adaptive system are part of the learning process, HSST constructs often stand outside of any pedagogical process.  (See #1 below)
  3. There are negative consequences associated with HSST.  Because of the lag time between testing and reporting, there is less instructional relevance to HSSTs.  Assessments in adaptive learning provide immediate feedback and are instrumental to the learning process.  There are also many unintended consequences, like instructional time that is wasted on test prep or the disassociation of error from an opportunity to learning.
  4. Assessments are consequential for students.  In adaptive learning assessments determines the instructional pathway the student will pursue.  If done well, the student will perceive this assessment to have been appropriate and helpful.  In many HSST (e.g. the SAT) assessments may be perceived as a threat and associated with a lack of opportunity.  See #2 below

It seems to me that as Adaptive Learning becomes more common and its validity become recognized, HSST will no longer be needed.

#1.   ”If the IUA does not claim much (e.g., that students with high scores on the test can generally perform the kinds of tasks included in the test), it does not require much empirical support beyond data supporting the generalizability of the scores. A more-ambitious interpretation (e.g., one involving inferences about some theoretical construct) would require more evidence (e.g., evidence evaluating the theory and the consistency of the test scores with the theory) to support the additional claims being made”.  Kane (2013) p.3

#2. “The SAT is a mind-numbing, stress-inducing ritual of torture. The College Board can change the test all it likes, but no single exam, given on a single day, should determine anyone’s fate. The fact that we have been using this test to perform exactly this function for generations now is a national scandal”. NYTimes

 

A New Form for Validity

December 24, 2013 by · No Comments · Validity

Thinking about new projects.  Here are the general contures of a new way of looking at validity.

  1. There have been criticism of Samuel Messick unified view of construct validity and Kanes Argument based approached.  I have yet to accept any logical argument made against either framework, yet I am sympathetic when it is said that these frameworks are not practical administratively.  
  2. Consider an argument made by the philosopher Karl Popper.  Popper makes a distinction between justification and criticism on the way to his famous idea of fallisficationism.  Just like one cannot claim that one’s theory is true through experimentation (you can only be sure of your results if they are false), so too it is precarious to justify one’s beliefs, but easy to demonstrate if their false.  Justification can be seen as a next to impossible task, but criticism is more likely to be seen as true.  If we respond to criticism with a desire to improve and adjust our beliefs than our beliefs will approach a closer version of what you might call truth.  So, the best way to justify assessment validity is by being open to criticism; always seeking to improve through critical reasoning.
  3. This does not nullify Messick’s framework (Messick, 1995), but it shifts it from justification to a framework for critique and critical thinking.  Messick’s framework moves from a hopelessly difficult attempt at justification and becomes a critical framework for knowledge transparency.  Recent developments in philosophy  have demonstrated the contingent nature and how the shape of knowledge is shaped by the form of its production.  Messick’s transparent critical framework for the production of assessment knowledge is the best way to see the underlying contingencies
  4. Kane’s framing of  validity as an argument is more suited to a critical approach than a justificationist approach.   The very nature of argument sets up a 2 sided dialogue.  Every argument presupposes a dialogic counter argument.  If you enter into an argument you must be willing to entertain and engage with critical position.  Kane’s framework is more suited to respond to critical than to depend on justification.
